REVOLVING COTTON PRESS.

SPECIFICATION forming part of Letters Patent No. 243,982, dated July 5, 1881.

Application filed April 9, 1881. (No model.)

To all whom it may concern:

Be it known that 1, JOHN M. SHAW, a citizen of the United States,residing at Water Valley, in the county of Yalabnsha and State of Mississippi, have invented Improvements in Revolving Cotton-Presses, of which the following is a specification.

The subject of my invention is a revolving cotton-press with two screws carrying pinions beneath the press bed or sill, which gear with a stationary cog-wheelof larger size, the screws having bearings also above the follower-block, in the upper part of the revolving frame. The follower-block is provided with open shoes or clutches to fit over or engage with the screwnuts, so as to facilitate the removingof said follower-block for filling the press. The follower-block also carries rollers working on trackways of press-box.

In the accompanying drawings, Figure 1 is a side elevation of my improved press, showing the follower-block elevated and press-box closed. Fig. 2 is a front elevation of the same,

showingthefollower-block up and thepress-box open and a bale ready for removal. Fig. 3 is a perspective view of the follower block detached. Fig. 4 is a perspective view of the upper part of the press-box, showing the followerblock moved from over the top of the press and the movable side-boards in position in readiness for filling in and tram ping cotton.

A A are standards connected by a horizon tal beam, A. The press-screws are shown at B B, having bearings in the bed plate or sill I, and having securely keyed on their lower ends cog wheels 0 O, which gear with a stationary center wheel,D,of larger diameter, the proportions preferably being such as to give the screws from one and a half to two turns for every turn of the press. The upper ends of the screws work in bearings j in the upper beams, J, of the revolving press-frame. The said frame consists of horizontal beams J J, connected by a transverse horizontal beam, H, and standards K K, connected at their lower ends by subsills L L, on which the main sill or bed-plate I rests.

M represents an ink or pivot in the center of the stationary wheel D,supporting the bottom of the revolving press-frame.

N is a gudgeon secured to the top of the press-frame, and turning in a suitable box in the upper stationary beam, A.

E represents a follower-block, having firmly secured to its extremities. clutch-shoes E, of metal, which have lateral notches c to receive and hold the flanged nuts F, and apply to the follower-block E the pressure derived from the rotation of the screws B B. The open slots in the clutch-shoes admit the ready removal of the follower-block whenever it is not under pressure.

On the under side of the follower-block, at each end, are rollers O 0, adapted to run on removable trackways P P,which are laid across the top of the box, beneath the ends of the follower-block,when it is run up. The said follower-block is then moved bodilyto one side to expose the top of the box for filling in and tramping the cotton. During this operation detachable side-boards S S are placed in position,as shown in Fig. 4. When the press-box has been filled and tramped the side-boards S S are removed, the follower-block E is run back into its operative position over the pressbox and engages with the nuts F, the trackways P P are withdrawn, and the press is then again ready for operation.

The press-box Q and doors R may be of ordinary construction.

The ends T T of the press-box are held in by key-pieces U U, having beveled lower edges, so that when pressed down they force the said end-boards firmly home and hold them out of contact with the screws.

My press possesses several advantages over any of the iron or wooden presses now in common use. It is speedy, and yet with an eight or ten foot lever a single mule can press a six hundred or seven hundred pound bale of cotton. It presses down evenly, making both ends of the bale the same size. It does not require large timbers to build it, and is not dangerous, and its construction permits it to be placed close to the lint-room, so that it may readily be covered over.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination of the revolving pressbox, the screws having bearings in the rotary frame both above and below the press-box, the

3. The combination of the detachable follower-block and the removable trackways onwhich the said block may be moved from over the press-box.

pinions keyed to the lower ends of the screws and gearing'with a stationary central Wheel, and the follower-block drawn down by the rotation of thescrews imparted by the revolution of the press on its own axis, as herein shown and described.

2. The follower-block constructed with open clutch ends or shoes, in combination with flanged or grooved nuts, over which the said clutch ends may he slipped, as herein shown and described.
